more political maneuvering around the nomination of chuck hagel as defense secretary. republican opponents say the vote should go forward unless more damaging material surfaces this week. the earliest that the nomination could go before the senate is a week from today. >>> and there's also plenty of political posturing over the issue of immigration reform. republicans and democrats are predicting president obama would fail if he pushes forward with his own effort to overhaul the system. under that white house plan, green card in eight years. top republican lawmakers don't like that. >> by giving advantage to those who cut in front of the line for immigrants who came here legally, not dealing with border security adequately, that tells us that he's looking for a partisan advantage. >> i hope that republicans and democrats up there don't get involved in some kind of typical washington back and forth sideshow here. and rather just roll up their sleeves and get to work. >> the white house says the president would push his own plan only if lawmakers cannot get the job done.
